Whoot! Now, to move all logging and other stuff there and see if it survives a reboot. I have to admit, I am not real impressed with how the card lugs into the unit. I also have to remember that this slot will not be available on a "retail" version (if say, I ever go into making one of these a product).

I tried a SDHC card and it worked fine. It is found as /dev/mmcblk0p1 so you can mount it with:<snip>

Where did you read that the SD slot will not be available on the "retail" version?

You know, I think I just assumed that when it talked about the mini-usb being on the dev kit. I have looked over all the web page info I can find and it is not listed as "only in the dev kit". I do see that the SDIO slot is part of the JTAG adapter card that contains the usb debug port.

I am looking at the "SheevaPlug DevKit Reference Design Rev1.1" pdf that is available on the site or on the cd. If the JTAG adapter board is only part of the development version (all there is now), then so be it. Still a hell of a deal for a server. I will pay $45 more for a box I can expand the disk on by 4-16 GB. My gut tells me SDIO would be faster access than usb disk. usb is still a very viable option. Right now, I am working on php and getting log/lib data from installed packages stored on the 4 GB SDIO disk.

I tried an 8 GB class 6 Kingston card with the uImage.sheeva.20090319 kernel a while back and it seemed to work. I doesn't work with uImage-2.6.30-rc2-optware-build-2. If I get a chance I'll switch back and verify that it worked with the other kernel. I really just did a few simple checks back then.

4G Sandisk Extreme III seems to behave the same as the 8G Patriot - it hits a speedbump when formatting at about the 26 block mark. Being a smaller disk than the 8G, it finished formatting (the Patriot more or less stopped, it was going so slowly).

I may try using it, but I'm a little nervous. I think the SDIO support is a bit weak.

So I have two Plugs. One was still virgin so I did some testing with it and my new 8 GB Kingson SDHC class 6 card. I installed it in the slot. It was found and devices added with no error messages. I mounted it as vfat and copied a bunch of files on to it (my /sbin directory) the only errors were about not being able to create links on a vfat drive. So it worked fine. I used fdisk to remove the current partition. Then I used cfdisk to add a new 8GB ext3 partition. I ran mkfs.ext3 to make file system mounted it and copied 'cp -av' the entire root file system on to it. No errors.

So the conclusion is the MMC/SD slot works fine with a virgin Plug. The problems seem to arrive with the mainline kernels.

edit: I restarted my modified slug and inserted the card as it was left off from the virgin plug.
